Improvement in Cloth-Cutting Machines, of

which the following is a specification.

My invention relates to clothcutting ma chines designed to be employedin cutting out clothing; and it consists in a certain novel constrnction and combination of devices, fully set forth hereinafter, inconnection with the accompanying drawings,and specifically pointed outin the appended claims.

In the drawings, Figure 1 is a perspective View of the cuttingmachineembodying my improvements. Fig. 2 is a transverse central sectional viewthereof. Fig. 3 is a detail view of the revoluble frame.

Referring by letter to the drawings, A designates the cutting-board,which is suitably supported,and in its center is formed an opening, or,having an inwardprojecting fiange,a',

at the lower side of the cutting-board. A frame, B, depends from thelower side of the cutting-board adjacent to the opening therein, and ina guide or way, I), in the said frame operates the guide-block G, whichis provided with lateral webs c c, which enter extensions 1) bof theguide or way I). This guide-block is provided on its outer side with thebearing cl, in which is mounted the socket-piece D, held in place by thepin d, and provided with a bifurcated or slotted upper end, (1".

E represents a horizontal shaft, which is mounted at one end in thelower end of the depending frame, and at the other end in one of thesupports F F of the cutting-board and the free or outer end of thisshaft may, if. desired, be provided with a crank to enable the shaft tobe rotated. The inner end ofthe horizontal shaft is provided with awheel, G, to which the guide-block is connected by means of theconnectingrod g.

H represents a bandpu1ley, which is at tached rigidly to a suitableportion of the shaft Rand adjacent to the band-pulley is the loose oridle pulley h, to which the driving-belt (not shown) may be transferredwhen the motion of the machine is to be stopped temporarily.

I represents a head,which is attached firmly to the meeting ends of theconvergent supporting-arms K K, which are arranged 011 thecutting-board, and this head is provided with a depending spindle, L, onwhich is mounted the socket m at the upper end of the revoluble frame M.The revoluble frame is provided with the depending parallel arms NN,which are provided in their sides with the registering guidegrooves a 21;and 0 represents a guide-block, which is arranged between the parallelarms,and is provided with the lateral webs, which slide in theguide-grooves n n. In the lower slotted end of this guideblock isarranged the upper end of the cutting-blade P, and the lower end of theblade is inserted in the slotted upper end of the revoluble socketpieceD. The ends of the blade are secured in place by transverse screws orpins 1) 1), whereby a broken or injured blade may be readily replaced bya new blade. An intermedi' ate point of the cutting-blade passes througha guide-opening, q, in the revoluble disk Q, which is arranged in theopening in the cuttingboard, and rests on the inward-projccting flangea, before described.

R It represent verticallyadjustable legs, which are connected to thedepending arms of the revoluble frame and are provided at their lowerends with the roughened friction-rollers r 1', which are adapted to beadjusted close to the cutting-board, so as to bear on the cloth which isbeing cut and hold the same down firmly on opposite sides of the blade.These legs are provided with longitudinal slots S S, through which passthe adjusting-screws '1 T, which engage in suitable threaded openings inthe arms N N, whereby the friction-rollers may be vertically adjusted tosuit various thicknesses of cloth.

The operation of the improved cutting machine will be readily understoodfrom the foregoing description. When the horizontal shaft is rotated,eithcr by a belt connecting with a suitable motive power or by means ofa crank, the guide-block in the depending frame is verticallyreciprocated, and the blade is thereby similarly operated,thus cuttingthe cloth which passes over the cutting-board under the rollers. When itis desired to cut around curves, it is simply necessary to turn therevoluble frame, thereby turning the blade, the socketpiece, and theguidedisk Q. It will be obvious that the said disk is designed toprevent lateral movement of the blade and cause it to operate in a truevertical plane.

To hold the revoluble frame in any desired position I provide a catch,U,which is attached to the said f1 ame near its upper end, and isadapted to engage sockets to a in the side of the head. The catch isprovided with a spring arm, U, which is held against the side of theframe by means of keepers it.

Having thus described the invention, I claim- 1. The combination, withthe euttingboard provided with an opcning,a, of the head I, suitablysupported above the board and provided with a depending spindle, therevoluble frame mounted on the said spindle and provided with dependinggrooved arms N N, the sliding guide-block O, mounted at its edges in thegrooves of the said arms, the depending frame B under the cutting-board,provided with a way or groove, 7), the guide-block e, mounted in thesaid groove or way, the revoluble socket-piece I), mounted on theguidebloek, the pulley G, connected by a rod, g, to the guide-blocks G,and the knife secured at its ends, respectively, to the block 0 andsocket-piece O, and passing through the opening in the eutti ngboard,substantially as specified.

2. The combination, with the eutting-board provided with the opening a,the depending slotted frame B under the cutting-board, the headsupported above the cutting-board and provided with a depending spindle,and the revoluble frame mounted on the spindle, of

the guide-block C, mounted in the frame 13' and provided with arevoluble socket-piece, D, the guide-frame O, mounted on the revolubleframe above the cutting-board, the blade attached at its ends to theguide-block O and the socket-piece D, the vertically-adjustable legs R Ron the revoluble frame and provided with longitudinal slot's, throughwhich pass set-screws T T, and the rollers mounted on the lower ends ofthe legs and bearing on the cutting-board on opposite sides of theopening .therein, substantially as specified.

3. The combination, with the cuttingboard provided with an opening, a,the depending frame 13 below the cutting-board and provided with theguide or way I), the head I, connected to the adjacent ends of theconvergent supports K K, and provided with a depending spindle, and therevoluble frame M, mounted on the said spindle and provided with thedepending grooved arms N N, of the guide-block O,mounted between thearms N N, the guide block 0, mounted in the guide or way I) and providedwith a socket-piece, D, the blade connected to the guide-block O andsocketpicee D, and extending through the opening a, the horizontal shaftprovided with a bandpulley and an idler-pulley, and the wheel on the endof the said shaft,connected to the block 0 by the rod substantially asspecified.

at. The cutting board, the head supported above the board, the revolubleframe mounted on the head, and the frame B,depending from the board, incombination with the guide-block O, mounted on the framcB, and providedwith a socket-piece, D, the guide-block O,mounted on the revolubleframe, the blade connected to the block 0 and the socket-piece D, andthe catch U on the revoluble frame, adapted to engage sockets to a inthe head, as and for the purpose substantially as specified.

5. The combination, with the cutting-board provided with an opening, a,having an inward-extending flange,a, of the guide-disk Q, mounted in thesaid opening and bearing on the flange therein, the head Lsupportedabove the cutting-board and having a revoluble frame provided withgrooved arms mounted thereon, the guide-block O, mounted on the groovedarms, the guide-block (J, mounted in a frame beneath the cutting-boardand having a revoluble socket-piece mounted thereon,and the bladesecured at its ends to the socketpieee and the block 0, and passingthrough a central elongated opening, q, in the guidedisk, whereby as theblade turns by the rotation of the revoluble frame and the socket-piecethe guide disk is also turned, substantially as specified.

In testimony that Iclaim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
